Many attempts have been made to create an accurate bolt rifle actionbedding method that consistently provides a solid base to mount anaction to a chassis or stock. There are a multitude of different typesof bedding methods from basically screwing to wood or composite typestocks which tend to be the least accurate to screwing to solid milledstocks formed from a single metal blank, which may be more accurate.Accuracy seems to increase when the action is bedded in a non-movablebedding configuration. Even the slightest movement of the action in thestock will reduce accuracy significantly. Due to the many companies andgunsmiths that manufacture bolt action rifles; and the multitude ofaction size variations, every rifle comes with its own unique stock. Ifa bolt action rifle owner wanted a new stock, they wouldself-manufacture or purchase a stock that fit their specific action.

Although bedding of an action is of prime importance to accuracy, ofequal importance is the ability of the shooter to have a consistentlength of pull, cheek height, sight plane, rifle balance and weight toname a few. This is hard to achieve based on the variance ofstock/action combinations and the caliber length. When rifles betweendifferent manufactures are shot by the same shooter, accuracy isgenerally reduced because of the inability of the shooter to maintainthat consistent feel and placement of the stock/action between differentaction combinations. The multitude of manufactures and their uniquedesigns and dimensions have required individual and costly chassis andstocks due to these dimensional variations maintain that consistent feeland placement of the stock/action between different action combinations.

Several types of modular stocks or chassis have been proposed ordescribed—for example U.S. Pat. No. 8,079,169 to Gregg (2011), U.S. Pat.No. 7,841,119B1 to Boyd (2010) and U.S. Pat. No. 6,293,040 (2001) toLuth. Additionally, U.S. patent applicant Eberle described with20040211104 (2003) a modular stock system. Although similar inmodularity, and in some application, usable with more than one boltaction style, in some applications the stock and chassis are fragmentedand reduce strength, thereby reducing accuracy. Also, some applicationsuse a specific unique manufacturing design that preclude the use ofother manufactures bolt action receivers, including single applicationtriggering systems. Other types of modular chassis and stocks requirethe use of components other than the action to be transferred from theoriginal stock or chassis to the described design, such as triggerguards or floor plates, creating more, not less exclusivity ofreceivers. My own application uses a chassis or stock shaped from asingle piece of material, not fragments that reduce the strength of thestock or chassis. My design of the Versa-Fit Modular Bedding block usesonly the existing receiver with no additions or removals of significantor insignificant parts of the existing chassis or stock, creating more,not less modularity and acceptance of a myriad of bolt action receivers.Nevertheless, all modular and non-modular stocks and chassis heretoforeknown suffer from a number of disadvantages:

-   -   (a) Limited number of production bolt action receiver        applications due to an additional existing parts use        requirements requiring multiple chassis designs.    -   (b) A loss of chassis strength due to a fragmentation of the        longitudinal configuration of the chassis.    -   (c) Additional cost of single application stocks and chassis due        to specific bolt action receiver design.    -   (d) Site in requirements after each bolt action receiver change        due to movement of action in bedding area.

SUMMARY

In accordance with one embodiment an integrated chassis and stock systemwith versa-fit modular bedding block consists of a chassis or stock witha recess that accepts a unique modular bedding block with its attachedbolt action and is held in place with a securing wedge or screw.

Advantages

The Chassis and Stock Integration System accepts the Versa-Fit ModularBedding Block and allows for multiple (virtually unlimited) bolt actiondesigns to be used in a single chassis system. There is no change in thefit of the rifle and the shooters individual preference remainconsistent based on the length of pull, cheek height, sight plane, riflebalance and weight, regardless of the variations of the actiondimensions and attachment design. A single shooter implementing themultiple modular bedding blocks can remove and replace the individualaction designs into a single chassis with no fit deviations, feel, orbalance issues. This method increases accuracy because of the securebedding of the action into its modular bedding block whilesimultaneously reducing cost, storage, and weight because one chassisfits all bolt actions designs.

Versa-Fit Modular Bedding Block,in one embodiment, the material of construction is metal, 7075 T6aluminum. Materials for other embodiments are only limited by thestrength and rigidity of the material. The 16 Wedge Locking Block in oneembodiment, is constructed of Stainless Steel. The strength andcorrosion resistance of Stainless Steel is preferred as the 16 WedgeLocking Block is the primary securing component of the Versa-Fit ModularBedding Block to the 12 Chassis or Stock. Other embodiments could behigh strength composites of various other metals with the ability to bethreaded and thread life the limiting factor. The 12 Modular IntegratedChassis is the component that securely holds the individual uniqueVersa-Fit Modular Bedding Block tightly in, on, or around the 12 (FIG.3); (FIG. 3C) Chassis or stock receiving location of the rifle chassisor stock. The 14 Versa-Fit Modular Mounting Block holds the bolt actionin the 12 Modular Integrated Chassis System, regardless of the 10(FIG. 1) bolt action dimensions on the interior of the 14 Versa-FitModular Bedding Block. The exterior dimensions of the 14 Versa-FitModular Bedding Block never change and fits into, over or around the 14Versa-Fit Modular Bedding Block receiving section of the (FIG. 1)Chassis Integration System. The 14 Versa-Fit Modular Bedding Block isheld in place in the 12 (FIG. 6) Modular Integrated Chassis System bymultiple means that securely holds the 14 Versa-Fit Modular BeddingBlock in the front and rear of the 20 Chassis Receiving section where itis aligned consistently and repeatedly with multiple alignment methods.

Operation FIGS. 1; 6 & 6.A

The 14 Versa-Fit Modular Bolt Action Bedding Block and 2 The ModularIntegrated Chassis System is designed for 10 bolt style actions. TheModular Integrated Chassis System is designed to be used in conjunctionwith the 14 Versa-Fit Modular Bedding Block and 16 Integral WedgeLocking Block. The (FIG. 6A) Chassis Integration System accepts the 14Versa-Fit Modular Bedding Block and allows for multiple (virtuallyunlimited) 10 bolt action designs to be used in a single chassis system.The 16 Wedge Locking Block secures and locks the 14 Versa-Fit ModularBedding Block in place. The 16 (FIG. 6) Wedge Locking Block, using the36 Wedge Locking Block Fasteners, is pulled vertically between theangular face of the 16 Wedge Locking Block and the 18 (FIG. 3A)

(FIG. 3D) Chassis Stop Block. The corresponding 34 (FIG. 6A) WedgeLocking Block Slide Face pushes the 14 Versa-Fit Modular Bedding Blockrearward and with the 22 (FIG. 3C); (FIG. 4A) Steel Alignment Pin and 24Collar hold the 14 Versa-Fit Modular Bedding Block securely in place in,on, or around the 20 (FIG. 3) Receiving Section of the 12 Chassis. The32 (FIG. 4); (FIG. 4A); (FIG. 4B); (FIG. 4C) Lateral Movement LockingSlot in conjunction with the 38 (FIG. 5); (FIG. 5A) Lateral MovementWedge Lock control lateral movement of the Versa-Fit Modular BeddingBlock within the 20 Receiving Section of Chassis. (FIG. 1) The ModularIntegrated Chassis and Stock System holds the 14 Versa-Fit ModularBedding Block securely in place and has the (FIG. 2) external dimensionsthat match the external dimensions of the 12 Modular Bedding Block sothat fit and finish of the two joined parts solidly mate for repeatableremove and replacement activities that are repeatable.

FIGS. 1; 3A-3B Alternative Embodiments

There are various possibilities with regard to the attachment of theVersa-Fit Modular Bedding Block. FIGS. 3A and 3B show that the 14Versa-Fit Modular Bedding Block can be attached with a single fasteneras shown as a screw access hole 7. This embodiment will remove the needfor the 16 Wedge Locking Block by using a screw fastener attachment ofthe 14 Versa-Fit Modular Bedding Block through the 7 Screw Access Holein the base of the Chassis or Stock. This method may be the preferredattachment in a situation where a heavy recoiling cartridge is used inthe (FIG. 1) The Modular Integrated Chassis and Stock System could causeadditional flexing of the actual 12 Chassis and reduce accuracy.Additional embodiments occur with the attachment of the 14 Versa-FitModular Bedding Block in various methods on or around a Chassis or Stockwith various means using threaded fasteners in the rear, top or bottomof a Chassis or Stock.

Advantages

From the descriptions above some embodiments of my Integrated Chassisand Stock System with Versa-Fit Modular Bedding Block become evident.

(a) The Modular Integrated Chassis System maintains the individualshooters preset fit and feel regardless of specific Modular BeddingBlock inserted with its corresponding action.

(b) The Modular Integrated Chassis System contains the wedge stop blockthat is used exclusively to provide solid mounting while directinglinear force through the Modular Bedding Block, by accepting the WedgeLocking Block as it is inserted into and properly torqued between thewedge stop block and the Modular Bedding Block

(c) The Modular Bedding Block is held in place in, on, or around thechassis or stock by multiple means that securely holds the ModularBedding Block in the front and rear of the Chassis Integration Systemsection where it is aligned consistently and repeatedly with multiplealignment methods.

(d) The Chassis or Stock Integration System accepts the Modular BeddingBlock and allows for bolt action designs to be used in a single chassissystem.

(e) There is no change in the fit of the rifle or the shootersindividual preference remain consistent based on the length of pull,cheek height, sight plane, rifle balance and weight, regardless of thevariations of the action dimensions and attachment design.

(f) This invention increases accuracy because of the Wedge Locking BlockSystem, while simultaneously reducing cost, storage, and weight becauseone chassis fits all bolt actions designs.

CONCLUSIONS, RAMIFICATIONS, AND SCOPE

Accordingly, the reader will see that the Modular Integrated Chassis andStock System holds the Versa-Fit Modular Bedding Block securely in placeand has the external dimensions that match the external dimensions ofthe chassis and stock so that fit and finish of the two joined partssolidly mate for removal and replacement activities that are repeatable.The Modular Integrated Chassis System also maintains the individualshooters preset fit and feel regardless of specific Modular BeddingBlock inserted with its corresponding action. Additionally, theversatility and cost reduction of one chassis system that acceptsmultiple styles of bolt action designs is both heretofore unachieved forthe common and un-common production bolt action receivers, as well asany number of custom embodiments.

Furthermore, this Modular Integrated Chassis and Stock System withVersa-Fit Modular Bedding Block has additional advantages in that:

-   -   each unique bolt action design will have its own properly        internally dimensioned Modular Bedding Block for accuracy and        flexibility.    -   bolt actions from same manufacturer and of same model can be        used interchangeably with a single Modular Bedding Block.    -   bolt actions from the same manufacturer but of different models        will have their own unique Modular Bedding Block for internal        dimensions.    -   the exterior of the Modular Bedding Block is dimensionally        consistent regardless of bolt action style, size, and        manufacturer.    -   is designed to securely hold the Modular Bedding Block in the        Modular Bolt Action Bedding Block and Chassis or Stock in a        constant linear stress free position.    -   There is no change in the fit of the rifle or the shooters        individual preference remain consistent based on the length of        pull, cheek height, sight plane, rifle balance and weight,        regardless of the variations of the action dimensions and        attachment design. A single shooter implementing the multiple        modular bedding blocks can remove and replace the individual        action designs into a single chassis with no fit deviations,        feel, or balance issues.    -   This method increases accuracy because of the Wedge Locking        Block System, while simultaneously reducing cost because one        chassis fits all bolt actions designs.
